Tore apart my entire car today to yank the heater core. What a PITA. Along the way I fixed /cleaned/oiled a bunch of other things, and I think my AC/Heater should actually work really well now, once I get everything sealed back up. Speaking of which... Does anyone have any recommendations for a cheap, complete, effective reseal kit for a 1966 Skylark with factory AC? I have found some online, but they all seem to show a picture of gaskets that are shaped like the heater only box... maybe this is just one of those "generic picture" situations? Any thoughts?
I forget where I got it, but I have some gray "dum-dum" type AC sealer. Works great on the old Skylark. It's on a roll, so I just reeled out what I needed, curved to fit and installed the box. Try a home AC vendor? Yeah, the heater core is a real sweetheart to change. On my '68 it required taking the hood and passenger fender off, if you don't know where or don't want to drill the hole for the socket. I left that nut off, after the second heater core.
I bought this kit for my 67, non-ac car. It has all the seals, but totally lacks an instruction sheet detailing what is a seal and what was just left over after die cutting. After cleaning and painting my box up, this worked pretty well for me, but it is still just sitting in a box now. The seal that fits around the heater core tubes is much thinner than the original one tho. The new one is maybe 3/8 thick and the original was 3/8 thick but stuck out the fire wall holes a good half inch beyond that. Not sure if the original was really thick to start with, or if it was multi-level.
